Double infection of the CNS with herpes simplex and mumps viruses. Serological and ultrastructural studies
Abstract:
Clinical, serological and ultrastructural features are described in a case of acute encephalitis. The ultrastructural study of brain biopsy specimens revealed herpes-and paramyxovirus-like particles in neurons and glial cells that were characterized as herpes simplex and mumps viruses by serological study in serum and CSF. Of the few cases previously reported with double encephalitis, this is the only one in which ultrastructural and serological evidence of combined brain infection has been found.
Insights
This study presents a rare case of acute encephalitis, identifying both herpes simplex virus and mumps virus co-infection. It provides crucial ultrastructural and serological evidence of this dual brain infection.
Area of Science:
- Neurology
- Virology
- Pathology
Background:
- Acute encephalitis is a severe neurological condition often caused by viral infections.
- Diagnosing co-infections in encephalitis cases can be challenging, requiring advanced diagnostic techniques.
Observation:
- A patient presented with clinical, serological, and ultrastructural features of acute encephalitis.
- Brain biopsy specimens were examined using electron microscopy.
Findings:
- Ultrastructural analysis revealed herpes-like and paramyxovirus-like particles within neurons and glial cells.
- Serological studies confirmed the presence of herpes simplex virus and mumps virus in serum and cerebrospinal fluid (CSF).
- This case is unique as it provides combined ultrastructural and serological evidence of dual viral encephalitis.
Implications:
- Highlights the importance of considering co-infections in severe encephalitis cases.
- Demonstrates the utility of integrated diagnostic approaches (ultrastructural and serological) for identifying complex viral pathogens.
- Contributes to the understanding of rare dual viral infections affecting the central nervous system.
